Sorry for late response.This coding was before stage3d(molehill) I was using .x .y and .z for position in space and .rotateX .rotateY .rotateZ for rotation of movieclips. Sadly I don't have the code, but right now you can use engines such as Flare3D to take advantage of the stage3d feature.

Its really amazing. I didnt even know someone could make this in flash! I like it very much, you could probably do this thing professionally (if you dont allready). This one in particualr makes me expect some zombie monster thing to jump trhough the door. xDreally impressive. Congrats!
